  • 1. 2110731 Distributed Systems Ubiquitous Computing Computer Engineering Department Chulalongkorn University Present by LogicalSync group Saturday, September 12, 2009 1
  • 2. Introduction • What is Ubiquitous Computing? • Ubiquitous means everywhere • From the past, to present and beyond to the future... Saturday, September 12, 2009 2
  • 3. Ubiquitous Computing • This term was coined by Marc Weiser of Xerox PARC around 1988 The purpose of a computer is to help you do something else. The best computer is a quiet, invisible servant. The more you can do by intuition the smarter you are; the computer should extend your unconscious. Saturday, September 12, 2009 3
  • 4. Three Waves of Computing •Main Frame •Personal Computer •Ubiquitous Computing Saturday, September 12, 2009 4
  • 5. Three Waves of Computing •Main Frame Many person - One computer •Personal Computer •Ubiquitous Computing Saturday, September 12, 2009 4
  • 6. Three Waves of Computing •Main Frame Many person - One computer •Personal Computer One person - One computer •Ubiquitous Computing Saturday, September 12, 2009 4
  • 7. Three Waves of Computing •Main Frame Many person - One computer •Personal Computer One person - One computer •Ubiquitous Computing One person - Many computer Saturday, September 12, 2009 4
  • 8. Moore’s Law • The number of transistors that can be placed inexpensively on an integrated circuit has increased exponentially, doubling approximately every two years. Saturday, September 12, 2009 5
  • 9. Computer is every where • Mobile Phone • Car • Refrigerator • Shoes (Nike) Saturday, September 12, 2009 6
  • 10. Key Elements in Ubiquitous Computing Let there be enlightenment Saturday, September 12, 2009 7
  • 11. Key elements of Ubiquitous Computing • Ubiquitous Networking • Ubiquitous Sensing • Ubiquitous Access • Ubiquitous Middleware Ubicomp required - Networking as a place to share data. - Sensing as eyes and ears to add more “ awareness” - Access from anywhere (mobile, wearable) and display with more natural - require less attention. - Middleware to shield application from low-level details Saturday, September 12, 2009 8
  • 12. Ubiquitous Networking Net working is a bare bone for ubicomp In order to access net work, we need “identification” to define which “thing” is accessing. Saturday, September 12, 2009 9
  • 13. Ubiquitous Sensing • Give systems “eyes and ears” • Adding more “Awareness” to Ubiquitous Network Pressure Sensor Voice Sensor • Automatic Measuring Acceleration Sensor Saturday, September 12, 2009 10
  • 14. Ubiquitous Access • Access from anywhere • Required less attention • Mobile Computer • Wearable Computer Wearable Computer Saturday, September 12, 2009 11
  • 15. Ambient Displays E-Ink weather Saturday, September 12, 2009 12
  • 16. Ubiquitous Middleware • Typically a software • Shield an application from low-level details • Interact with Ubiquitous Networking, Sensing and Access Saturday, September 12, 2009 13
  • 17. How does it works? Putting them all together Saturday, September 12, 2009 14
  • 18. Identification Who am I speaking with? Saturday, September 12, 2009 15
  • 19. Identification • Radio Frequency Identification (RFID) • Provide an identity to things • Book • Clothes • Active - has battery • Passive - harvest energy from reader • Main area of use is in retail supply chain • Mobile phones with embedded RFID is being used in Japan Saturday, September 12, 2009 16
  • 20. Identification • Radio Frequency Identification (RFID) • Provide an identity to things • Book • Clothes • Active - has battery • Passive - harvest energy from reader • Main area of use is in retail supply chain • Mobile phones with embedded RFID is being used in Japan Saturday, September 12, 2009 16
  • 21. Identification • Visual bar codes • QR Codes (Quick Response) is widely used in Japan • Drawback is rely on user action rather than “Automatic” Saturday, September 12, 2009 17
  • 22. Identification • Visual bar codes • QR Codes (Quick Response) is widely used in Japan • Drawback is rely on user action rather than “Automatic” Saturday, September 12, 2009 17
  • 23. Location Where am I now? Saturday, September 12, 2009 18
  • 24. Location • The ability to locate objects/devices current location • Global Positioning System (GPS) • Mobile Augmented Reality Application - Layar Saturday, September 12, 2009 19
  • 25. Location • The ability to locate objects/devices current location • Global Positioning System (GPS) • Mobile Augmented Reality Application - Layar Saturday, September 12, 2009 19
  • 26. Context Awareness Relevant information in the right form, time and place Saturday, September 12, 2009 20
  • 27. Context Awareness • Intelligent Agents which can “learn” • Voice analysis, Gaze tracking, from experience Machine vision • Respond to environmental data • Emotional Awareness • Sensor detect your friend come to the room, room’s temperature is cooling down • Sensor detect you are in the cinema, so the phone won’t ring Saturday, September 12, 2009 21
  • 28. The Aware Home A prototype of Ubiquitous Computing application Saturday, September 12, 2009 22
  • 29. A living laboratory for Ubiquitous The Aware Home Computing Saturday, September 12, 2009 23
  • 30. Issues in Ubiquitous Computing Today’s problems and solutions Saturday, September 12, 2009 24
  • 31. Issues in Ubiquitous Computing • Privacy - How can I trust the others • Reliability / Availability - Always on network • Smart Sensors - Are currently in research / development • Social Impact - It changes our life style Saturday, September 12, 2009 25
  • 32. Summary Ubiquitous Computing is all about Human! Because we love comfortable living Sci-fi movie is not far from reality Saturday, September 12, 2009 26
